What I find so notable is that no one who says it's a fanciful notion that Bitcoin will reach $250,000 in the specified time range says much else other than "I think it is too high a price ... no one can predict the price of BTC."
Well, here are some more grounded reasons for why this is possible:
1. The recentralization of Bitcoin as per the original message in this post
2. The increase in value mining (aka yield farming) which will tie exponentially higher sums of BTC up (just look at the increase in market cap of WBTC lately) and the BTC re-buying effect that such assets, where the relative per unit value with strengthen enormously over a very short space of time
3. Let's consider 18m supply @ $250,000 per BTC for a minute in real terms - that is 4.5 Trillion market cap. The highest the crypto market ever got was about $800b - near enough $1T (remember that? and Vitalik was banging on about how we hadn't really earned a trillion of value, about which he was dead right.- that was in 2018.) Now, that is about 4%-5% of the official market cap for all fiat currency worldwide. For the unofficial market cap - derived from adding in off balance sheet holdings from firms like Google etc. - that is about 2.5% of the global sovereign currency value market cap (gross value is a better term).
4. We need to be able to assume that Bitcoin can easily buy over $250,000 of assets daily. Is this realistic. To do this equation let's go back to DeFi. Now, Let's consider on their own, SNX MKR and COMP. That's about $1.2 billion of value there that has materialized in the past year (roughly) or about 0.5% of the entire market. This value stores on top of it roughly the same amount over the long term, say another half percent. We would expect to see such assets increase by about approximately 100x in value if a $250k value was justified for BTC. Given these assets almost like-for-like mimic ETH in the early stages in terms of price performance, and given that, well, these assets STORE those assets inside them further compounding such gains (hence shortening the timeline of price ascension) the rationale seems perfectly logical here.
Just my two cents of course - and everyone is entitled to their own opinion, but the financial case (if not so much the technological case, although that one is not too bad either) for at least $250k BTC appears perfectly sound.
